...Kenneth A. Rasmussen; Robert I. Haddad; A. Conrad Neumann Abstract The stable-isotope composition (δ 13 C) of total organic carbon (TOC) was measured as a function of depth throughout a 217-cm-thick sequence of Holocene carbonate sediment within the Bight of Abaco lagoon, Little Bahama Bank...

...A. C. Neumann; L. S. Land Abstract The 7 m deep Bight of Abaco, 80 x 35 km in size, is a semirestricted marine lagoon on Little Bahama Bank. A community of Thalassia and calcareous green algae grows on and contributes to a 2 m thick sediment carpet of calcareous muddy sand, which is accumulating...

... in North Sound, which is similar to that found in the Bight of Abaco in the Bahamas, is a record of transient depositional environments that evolved in response to the Holocene rise in sea level. Holocene sea-level curves, based on dated corals (e.g., Lighty et al. 1982 ; Fairbanks 1989 ) and basal...

...FIG. 14 —Detail of computer-enhanced Landsat image depicting tide-dominated margin. Large, bankward or flood-oriented sand lobes have migrated into lagoon (Bight of Abaco). Sand bodies behind small rocky cays or islands also suggest dominant bankward transport. Narrow, localized zone of dominant...

..., hydrodynamic, bathymetric, granulometric, and field observations of modern tidal systems in the Bahamas provides insight into this fundamental question. Oolitic tidal sands in the northern Abacos display a geomorphic pattern in which bedrock islands restrict and focus tidal flow down a main channel. Within...

... that the disaggregation f calcareous algae in the Bight of Abaco, a semirestricted marine lagoon on the Little Bahama Bank, produced one-and-a-half to three times the mass of aragonite mud and Halimeda sand now in the basin. Stockman et al. (1967) estimated that the contribution of sediment by Penicillus could account...

... sorted medium-grade sand. The traces of calcareous mud in the sands contain no evidence of “drewite” needles, which are restricted to the protected “shelf lagoons” west of Andros and Abaco Islands. The controlling factor in the formation and distribution of the sands is the tidal currents of cooler...

Possibly the restriction of those species to seagrass-vegetated localities at San Salvador is a preservational effect, because...
